Why does Psychology as a subject have a lot of anomalies?

Psychology is an empirical science. Its aim is to describe and explain human experience and behavior, their development in the course of life and all internal and external causes and conditions that are relevant for them.

The fact of being an empirical science, that is, that it cannot verify through the scientific method the veracity of its affirmations, postulates and theories, makes psychology base its concepts on the repetition of behaviors and not on the scientific confirmation of its theories. For this reason, many anomalies usually occur in this science, which arise from the fallible methodology that psychology uses to elaborate its theories.
